Testing Information

Note

The reliability of results is dependent on compliance with the pre-analytical and analytical conditions recommended by BioPredictive. The Tests have to be deferred for: acute hemolysis, acute hepatitis, acute inflammation, extra hepatic cholestasis. The advice of a specialist should be sought for interpretation in chronic hemolysis and Gilbert's syndrome. The Test interpretation is not validated in liver transplant patients. Isolated extreme values of one of the components should lead to caution in interpreting the results. In case of discordance between a biopsy result and a Test, it is recommended to seek the advice of a specialist. The cause of these discordances could be due to a flaw of the Test or to a flaw in the biopsy: i.e. a liver biopsy has a 33% variability rate for one fibrosis stage. FibroTest is interpretable for chronic hepatitis B and C, alcoholic and non-alcoholic steatosis. ActiTest is interpretable for chronic hepatitis B and C.
